With the spark plug wire disconnected and 
grounded, hold the blade control handle against the 
upper handle, and pull the starter rope out of the 
engine. Release the blade control handle. Slip the 
starter rope into the rope guide. Tighten the wing 
nut. See Figure 5.

Make certain all nuts and bolts are tightened 
securely.

Attach cables to the lower handle with the two cable 
ties already on the lower handle, insert pegs on 
cable ties into the holes on the lower handle. Pull 
cable ties tight and cut off the extra. See Figure 6. 

Figure 6

Converting to Side Discharge 

Your mower has been shipped as a mulcher. To 
convert it to a side-discharge mower, lift the 
mulching plug. Slide the two hooks on the side-
discharge deflector under the hinge pin on the 
mulching plug assembly. Lower the mulching plug. 
See Figure 7.

SECTION 4:  KNOW YOUR LAWN MOWER

Compare Figure 8 with your equipment to get familiar 
with the mower controls before operating it. 

Blade Control Handle

The blade control handle is located on the upper handle 
of the mower. The blade control handle must be 
depressed in order to operate the unit. Release the 
blade control handle to stop the engine and blade.

WARNING: 

This control mechanism is a

safety device. Never attempt to bypass its
operations. The blade will be rotating
whenever the engine is running.

Throttle Control

Your engine is equipped with a constant speed throttle, 
which is set at full throttle for best performance.

Starter Rope

The starter rope is attached to the handle. Stand behind 
the unit and pull the starter rope to start the unit.

Primer

The primer is used to pump gas into the carburetor. Use 
it to start a cold engine, but do not use it to restart a 
warm engine after a short shutdown. 

Mulching Plug

The mulching plug is used only for mulching purposes. 
This process recirculates the clippings back to the lawn. 
Do not operate the mower if the mulching plug is not 
firmly situated on the unit.

Cutting Height Adjustment Lever

This lever, located at each wheel, lets you adjust cutting 
height of the grass. Remember to put all four levers at 
the same height to avoid uneven cut.
